Hello There........
When Alberta and Harry M Hainsworth, returned to England , From South Africa , April 30th 1934 aboard The Warwick Castle, they gave the address I'del Old Road , Stanningley, near Leeds, as the address they were staying at......Do's that address mean anything to you ?
There is a H M Hainsworth , on a Medal Roll , for The Cape Government Railway ,South Africa.
Service Date 1899-1902. This would explain why Harry is missing from 1901 census.
I am not sure if this is any help really.

PS I have a feeling, that the address gven was Idle Old Road, Stanningley
